Many studies have demonstrated the usefulness of repetitive task practice by using robotic devices, including Lokomat, for the treatment of lower limb paresis. Virtual reality (VR) has proved to be a valuable tool to improve neurorehabilitation training. Our pilot randomized clinical trial aimed at evaluating the correlation between the modifications of brain oscillations during a VR neurorehabilitative training of gait and the motor function recovery in patients with chronic stroke.
